My invention relates to 'a combination door spring and stop device the object of which is'to provide an attachment for doors havlng a spring for resist ng the opening movement of a door and'normally holding it closed and further means operating in conjunctionwith said spring to positively prevent a door from being swung openbeyond a certain predetermined position. It is obvious that the latter function ofmy device prevents a door from being swung back accidentally or by a strong Wind'in' which case anyglass in the door easily broken or other damage may occur. {A further ob-' ject is to provide a simple,}eflicient and inexpensive device for the" purpose described and as illustrated in the accompanying drawing, n which,

Fig. 1 is a top vievv o f finy device in op erative position connected "with an outer door of a building, portions ofthewall adv lten'sedzsomewhat when the door is closed. 16

I have alsoprovided a-stoppdevicecome prising an 'VL-shaped finger-operated cam 17 pivotally secured as at 18 to the door 11 just below member 14 (seeFi'g. 2).one arm of said cam being bent'out as 17A and adapted to be swung into the path of stop arm 16$ 7 and outwardly thereof on the door (see Figs; 5 and 6). WVhen- 'the rod 16 is thus" prewhichsaid stop member comprises aybell crank lever pivotally securable to the door near itsspring bracket, a pro ect1on onone arm of's'aid lever adapted to be swung into contact with the outer ,part of the said hook on the rod when said hook is 'in'e'ngaging' position with the door bracket for thepurpose described. a

vented from sliding it is obvious that the door will be securely held in open position.

The use of my device has been fully dis} closed in" the fo'regoing' specification. It' might-be addedhowever'that in the mounting of my device the rod 16 may need'to be sprung at the end protruding from the *springso that its free endwill be parallel to'the adjacent face of the door and will thus not contact with or mar the door when being drawn toward the spri ng end Iclaim: 4 p I j 1.
